Description
Technical Field
The invention belongs to the field of compatibility of a server main board and a power supply, and particularly relates to a circuit structure for improving compatibility of a power supply module and the main board.
Background
With the continuous development of technology, the times of big data, cloud computing and artificial intelligence based on the Internet come. The data volume of the internet is increased drastically, the calculation amount and the calculation frequency are increased, and the number of data center servers is increased continuously. The total power consumption of each rack position in the data center is fixed, the protection is triggered beyond the total power consumption limit, the total power consumption also determines the number of servers which can be placed in one rack position, and the whole power consumption information of each server is monitored in real time. This places higher demands on the power management on the motherboard.
In the server system, PSU modules (power supply units: power Supply Unit) are adopted to supply power to the server, and one PSU module can meet the power supply requirement of a rack-mounted server in general, but two PSU modules are used for redundancy in the current design, and when one PSU module fails unpredictably, the other PSU module can continue to ensure the normal operation of the server. Different clients have different customizing requirements, and some clients require a server to use one PSU module to supply power, as shown in fig. 1, in this case, a standby path on a server main board is in a suspended state, and for some PSU modules, signal interference caused by the suspended state can influence normal operation of the server main board probabilistically.
This is a disadvantage of the prior art, and therefore, in view of the above-mentioned drawbacks of the prior art, it is necessary to provide a circuit structure for improving compatibility between the power module and the motherboard.
Disclosure of Invention
The invention aims to provide a circuit structure for improving the compatibility of a power supply module and a main board so as to solve the technical problem, wherein the circuit structure aims at the defect that the suspending state can cause interference to the main board when a standby power-taking path on the main board is not connected with a PSU module.
In order to achieve the above purpose, the present invention provides the following technical solutions:
the circuit structure for improving the compatibility of the power supply module and the main board comprises a PSU power supply module and a server main board, wherein the server main board is provided with an electricity utilization module, and the electricity utilization module is connected with a first electricity taking end and a second electricity taking end;
the first power taking end is connected with the PSU power supply module;
a first current node a is arranged on a line between the first power taking end and the PSU power supply module, the first current node a is connected with a reflux path, and the reflux path comprises a first matching resistor R1;
the voltage value of the reflux tail end of the reflux passage is smaller than the starting voltage of the power utilization module;
the second power taking end is connected with a voltage setting circuit, and the voltage setting circuit comprises a second matching resistor R2;
the voltage value of the voltage setting circuit is smaller than the starting voltage of the power utilization module. The original suspension state of the second power taking end is set to be a low-level state by the voltage setting circuit, so that the defect that external interference is introduced to a server main board from the suspension second power taking end is avoided.
Further, the power supply system also comprises a standby PSU power supply module; the return path has the same structure as the voltage setting circuit. The PSU power supply module is opposite to the standby PSU power supply module, when the PSU power supply module fails, the standby PSU power supply module starts to work, at the moment, the reflux passage can play a role in voltage setting, meanwhile, the PSU power supply module stops working, and the voltage setting circuit only performs reflux at the moment, so that the work of the power utilization module is not influenced. Therefore, the reflux path and the voltage setting circuit have the same structure, and the PSU power supply module and the standby PSU power supply module can work independently.
Further, the first current node a is connected with a first matching resistor R1, and the other end of the first matching resistor R1 is grounded;
the second power taking end is connected with a second matching resistor R2, and the other end of the second matching resistor R2 is grounded.
Further, the first matching resistor R1 adopts a resistor with a resistance value of 1mΩ, and the second matching resistor R2 adopts a resistor with a resistance value of 1mΩ. The resistor with the large resistance value of 1MΩ is used for having smaller influence on the voltage of the power module when the power module of the PSU works, and providing a low voltage state when the power module of the PSU does not work.
Further, a first voltage filtering module and a second voltage filtering module are also arranged on the server main board; the first voltage filtering module is arranged between the first power taking end and a circuit connected with the power utilization module;
the second voltage filtering module is arranged between the second power taking end and a circuit connected with the power utilization module. The first voltage filtering module and the second voltage filtering module are used for filtering the voltage and preventing interference in the voltage of the PSU power supply module from being introduced into the server main board.
Further, the first voltage filtering module comprises a first and gate, and the first and gate comprises a first input end, a second input end and an output end;
the output end of the first AND gate is connected with the power utilization module, the first input end of the first AND gate is connected with the first power taking end, and the second input end of the first AND gate is connected with a first reference voltage source;
the second voltage filtering module comprises a second AND gate, and the second AND gate comprises a first input end, a second input end and an output end;
the output end of the second AND gate is connected with the power utilization module, the first input end of the second AND gate is connected with the second power taking end, and the second input end of the second AND gate is connected with a second reference voltage source. The logic device AND gate is adopted as a voltage filtering module, the reference voltage value of the reference voltage source at the second input end is taken as a 1, is the standard value of voltage filtering, and is taken as a 0 when the voltage value input at the first input end is smaller than the reference voltage value, and the output end is 0 and is not output; when the voltage value input by the first input end is greater than or equal to the reference voltage value, the output end is 1 as a 1, and the voltage output plays a role in filtering the voltage value.
Further, the first reference voltage source and the second reference voltage source each use a reference voltage of 3.3V.
Further, the second input end of the first AND gate is also connected with a first filter circuit, and the second input end of the second AND gate is also connected with a second filter circuit. The first filter circuit and the second filter circuit ensure the stability of the reference voltage value and indirectly ensure the accuracy of the input voltage value of the server main board.
Further, the second input end of the first AND gate is also connected with a first filter capacitor C1, and the other end of the first filter capacitor C1 is grounded;
the second input end of the second AND gate is also connected with a second filter capacitor C2, and the other end of the second filter capacitor C2 is grounded.
Further, the first filter capacitor C1 adopts a capacitor of 100 nF; the second filter capacitor C2 adopts a capacitance of 100 nF.
The invention also provides a server, which adopts the circuit structure.
The invention has the beneficial effects that:
the compatibility of the server main board with PSU power supply modules of different numbers and different models is improved by optimizing the main board hardware design, and when a client requests the server to supply power by using one PSU power supply module, the power taking end originally connected with the standby power supply module on the main board is set to be in a determined low-level state through the voltage setting module, so that external interference of the power taking end in a suspended state is avoided from being introduced into the server main board.
In addition, the invention has reliable design principle, simple structure and very wide application prospect.
It can be seen that the present invention has outstanding substantial features and significant advances over the prior art, as well as the benefits of its implementation.
